Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The unit is sonically sealed, which means that water will not get into the light and damage the diodes or circuit board.

Surface-Mount Light

Surface mount light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the trailer.

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL181ARCRB Review

Speaker 1: Today we're taking a look at the Optronics LED Trailer Fender Clearance Light. This dual clearance light installs on your trailer fender, so one side is amber, the other side is red. Amber always faces the front of the trailer, red always faces the rear of the trailer.The assembly is reversible, so it can be installed on either the driver side of passenger side fender. It features a sonically sealed waterproof design, so it is submersible. It contains two LEDs, one amber, one red. LEDs are designed to make great replacements for incandescent lights.

They last longer, they burn brighter, and they're much more efficient. You don't have to worry about replacing bulbs or worry about brittle filaments with LED systems.The unit also has the clear polycarbonate lenses. They're very strong and durable, and it has the chrome-plated plastic ABS trim piece that snaps over the unit for a clean, finished look. It covers your hardware. These right here are your mount holes.

To gain access to those, you will need to remove the plastic chrome piece. Mounting hardware is not included, but it is a surface-mount installation.You'll notice that it's a two-wire design, black wire's for power, white wire's for ground. It is SAE and Department of Transportation compliant. It's a P2 rated unit.Taking a look at the dimensions real quick, edge to edge going this direction measures about 1 3/4 inches long. The overall width is an inch and a quarter.

The overall depth or thickness, that's how far it sticks out from the installation area, that measures 13/16 of an inch deep. Our mount holes right here are separated on center apart from one another by 1 inch.We're going to go ahead and hook it up to power, that way you can see what it looks like with some power running to it. We'll also turn off our overhead lights so you can see it in a lower light setting. Here you can see it sends out a really nice consistent signal. We have red on this side, amber on this side.

Total it contains two diodes, one per side, so the multi-diode design really helps optimize the overall light output. When it comes to the power draw at 12.8 volts, we're looking at 0.04 amps, and Optronics puts a lifetime warranty on their LEDs.That's going to do it for today's look at the Optronics LED Trailer Fender Clearance Light.

It came fast. Hooked it up and is still bright today. One year later I'm Very very happy with this light. Will be ordering more for my other trailers when I change the lights. 794647


This LED light is exactly what I was looking for. It is easy to install , very bright for such a small unit and submersible. 772602


Lights were exactly as described and worked perfectly on my fenders. The fenders are diamond-plate and these were small enough to fit well between the tread profile on the fender. My fenders also have wire management inside the fender so these worked very well and provided a nice, clean look as far as how they look after installation. 719238

Ask the Experts about this Optronics Trailer Lights

  • Troubleshooting LED Reversible Lights That Turn On When Trailer Battery Is Charging
    No. The # MCL181ARCRB should operate in the same manner as your regular lights, so they shouldn't come on when the battery is charged. This would lead me to believe there is something going on that was bleeding power to the lights or the lights are connected directly to the battery instead of the running light circuit on the trailer. If you can confirm that they've been installed on the running light circuit and not directly to the battery, let me know and I can give you a few other...

  • Chrome Trailer Clearance Light
    We do have a chrome light but it's not exactly the same as the clearance light # MCL180ARB. Part # MCL181ARCRB is chrome but not the exact same design. It's the closest we have though.
